SKATE snnnrnnnr..

Application led March 29, 1926. Serial No. 98,314.

This invention relates to skate sharpeners, and it consists ot certain novel constructions, combinations, and arrangements of parts, as will be hereinafter-fully described and spe-4 5 cilically claimed.

Referring to the accompanying drawings wherein the same numerals ot reference inw dicate like parts throughout the several views- Figure l represents a. side elevation of the device showing the adjustable guide withdrawn and a. sectional view of a skate runner. r

Figure 2 is a side elevation of the device in operative position with respect to the skate ruimer.

Figure 3 is a sectional view ot the housing of the device on line 3-3 ot Figure l, and full view of the cutting disc.

Figure l is a reverse side elevation ot the device minus the guide piece.

Figure 5 is an edge view of the device.

Figure 6 is a detail side elevation of the guide, and

Figure 7 is a perspective view ot the same.

The device consists ot the hardened steel disc l enclosed within the two part housing 2, 3, and is rotatably mounted on the central rivet l located at the central depressions 5 ot the housing. This rivet, or screw, as the case may be, not only forms a bearing tor the disc- 1, but it also serves to unite the two part housing or case.

The opening 6, Figure 4, of the housing exposes a su'Hicient portion ot' the disc l i'or the cutting operating presently to 4be described. 7, 8, are opposed recesses sunken in the two sides of the housing to receive the 40 continuous spring loop guide 9,. shown. in

Figure 7. This guide is adapted to straddle the housing and frictionally seat itself in the recesses 7, 8. l0, 1l, are small reverse depressions to afford a stop for the guide and thus limit its outward movement, while the spring grip exerted by the guide will main tain it in any position within the recesses 7, 8, the stops l0, 11, will prevent its displacement therefrom.

l/Vhen using the device, its disc 1- is brought in contact with the upper concave edgevof the skate runner l2, and the guide 9L pushed out against the stops to straddle the skate runner, as shown in Figure 2. The device is then slightly tilted to bring one of the edges of the disc in cutting engagement with the skate runner and is drawn lengthwise thereagainst to sharpen the same. The proper curve of the gutter or concave edge of the skate runner is governed by the periphery of the disc.

The advantage of making the guide of one continuous spring loop over an individual guide tor each side ot the device, is that both sides operate in unison and require no special means for retaining it in operative position. lvaking the guide ot rectangular wire will etlectually remove the burr thrown out by the cutting disc. i

It can vvery readily be seen that the recesses in the sides ot housing or case could be easily reversed to conceal the guide when withdrawn. In other words, these recesses could be stamped tromthe inside wallsof the case before it is assembled. The transverse opening through the periphery of the housing permits the use ot' either edge ot' the hardened disc.v

The device as shown and described forms a cheap, simple, small and ellective tool well adapted to be carried in the pocket.

Having thus described my invention what I claim is 1. A sharpening device of the character described, comprising a two part circula'rly .shaped housing, means tor connecting said parts to form a unit, a hardened disc mounted to rotate on said connecting means, said housing having a transverse opening through its periphery to expose a portion ot the disc, a spring loop guide ot a single piece of wire embracing the disc and said opening, and having a radial movement to and from the axis ot the housing.

2. A construction as in claim 1, in which recesses are formed in the sides of the housing to-provide locating seats for the guide.

K 3. A construction as in claim l, in which means are provided in the guide recesses to limit theoutward movement of the guide.

ln testimony whereof I atliX my signature.
